Oncers are counting down the days ’til we’re finally reunited with our friends in Storybrooke and the Enchanted Forest! But in the meantime, here are four things we can look forward to this season with absolute certainty…though some details may be open to creative interpretation as the season goes on!

4. The 100th episode is coming up and it’s gonna be CRAZY MAGIC

The 100th episode was teased at San Diego Comic-Con and at D23, but not much is known about it. There’s talk of it being a musical episode, and several cast members brightened up when the idea was mentioned.

Adam Horowitz, series co-creator, alluded to it very vaguely:

We want to make it very special, and we want the 100th episode to be our spring premiere. We’re hard at work trying to not to tell you anything.

What’s a Disney movie or show without some music? We’ve had so little of it these past four seasons that it seems like it’s time for a number or two already! Ursula’s singing and Snow White’s whistling are nice little nods, but I’m looking for a full-on community sing!

“A ha’penny? C’mon, guys, I’m literally singing for my supper!”

“This is the last time I answer a Craigslist ad for housekeeping.”

3. Emma isn’t going to fight the Darkness as much as she’d like to think she is

Jennifer Morrison, who plays the main hero and Savior Emma Swan, tells fans:

Emma went through a lot in her life. She had a tough childhood. She’s had to overcome a lot of things. She’s tried to be the bigger person. Now that she’s going to face the darkness, she’s free of that… She’s going to face the darkness in herself and figure out how to overcome it.

GOOD, I say! I don’t like static characters. Not that Emma hasn’t grown a lot since we first met her (and since her days in foster care), but we’ve never really seen her let go before. Sure, she’s thrown some punches, extracted her revenge via Regina’s apple tree, and shot Cruella in the chest when the villainess kidnapped Henr, but we’ve never seen Emma’s powers go truly dark before. Emma is a good person, and she’s a hero, but that doesn’t mean she’s perfect. I want to see her push the limits and explore the side that she didn’t really know she had. I want to see who she becomes after she finally gets to know all herself.

Remember kids, apples are a gateway drug to Evil!

2. Merida isn’t going to be a solo act

Horowitz made sure to entice fans with this teaser:

We’ve always wondered what would happen if Belle and Merida went on an adventure together. We hope you do, too, because it’s coming!

I would love to have heard that Merida and Mulan were going to partner up, but Merida and Belle sound just as amazing! Belle’s life is going to change so much this season. Rumple may or may not have magic, so he’s going to need to recover and readjust to no longer being the Dark One. And Belle may or may not stay with him romantically. Belle’s sense of adventure will most likely be sparked by this new, non-flouncy princess who would rather have a ball than dance at one. I’d really like to see Belle re-energized. She’s one of my favorite characters in both Disney and OUaT, and I think she deserves more credit and opportunities to shine without Rumple around.

“Hey, wait a minute, this master script says Belle is supposed to have her own house, her own bank account, and her own car by season 3! CARLYLE! GET OVER HERE!!”

1. Merida will not be Zelena and Robin’s daughter

I can’t even begin to express my joy over this news. Honestly, it was my least favorite fan theory ever. Horowitz gives it to us in no uncertain terms.

It’s just a fun theory, but the reality is we are sticking to the canon of the movie Brave in terms of who her parents are and where she came from, but post-movie is where our Once Upon a Time spin comes into play.

Which sea goddess do I bow before? Which Fairy do I bring gifts to? Is there a Rock Troll that needs more moss? I cannot begin to express my gratitude. Zelena is the embodiment of insecurity and selfishness. Merida is, in a word, BRAVE. And I refuse to believe that Zelena could ever be worthy of a daughter like Merida.
